Helmet gamer JBL Quantum 350 Wireless is a wireless model with a fairly simplistic design. It is intended to be light with just over 250 grams on the scale and seems to offer a correct autonomy of more than 22 hours.

Offers at the recommended price of 99.99 euros, it works logically using a 2.4 GHz connection and has a removable microphone essential for voice communications from players and your long evenings spent on Discord. After a few days in his company to test it, it’s time to give you our full opinion.

Technical sheet

This test was carried out using a product lent by the brand.

A very classic helmet

Out of its box, the JBL Quantum 350 Wireless surprises first of all with its weight. Not exceeding 252 grams on the scale, the JBL headphones are however not helped by the materials chosen by the brand which make it look like a toy while not necessarily predicting a good lifespan.

For the rest, the Quantum 350 Wireless is a fairly standard helmet made up of a relatively flexible metal hoop covered with plastic. Sporting the brand’s logo on the upper, it is covered in a foam that is clearly lacking in padding. A small defect which is ultimately not so disabling as that due to the limited weight of the helmet.

The headband is adjustable thanks to a sliding system which would have benefited from being better marked, but which has the advantage of having a real scale, allowing you to easily retain the setting that suits you best. The amplitude offered by this arch allows the Quantum 350 Wireless to be ” compatible » with the biggest heads.

The earcups rotate 90°, allowing the headset to fit comfortably around the neck when not in use. The latter are logically adjustable in all directions to adapt to the morphology of the user. They also benefit from very basic leatherette pads as well as the foam used which does not seem to be of very good quality.

Real magnets for fingerprints with their shiny plastic coating, the earpieces host the brand logo in their center. RGB point here, which is not displeasing to us. The right ear cup only houses the power button, associated with an LED indicating the status of the headphones. All the other buttons and connectors are relegated to the left atrium.

We take advantage here of a volume control wheel that lacks resistance and which is not associated with the Windows volume. This therefore implies that it will be necessary to manually modify the volume of the system if it is not high enough. A button is also present to mute the removable microphone which is installed at the front, via a jack connector. The thin shape memory pole is generally convincing and sufficiently long and the microphone is equipped with a windscreen which makes it possible to attenuate hissings and “pops”.

On the connection side and beyond the wireless link, the Quantum 350 Wireless has a USB type-C port which will only be used to charge the integrated battery. It will therefore not be possible to use the wired headset. We also don’t have a jack port that would have allowed the headset to be used on the vast majority of devices.

Once the helmet is screwed on the head, its lightness very clearly serves its comfort. Used for several hours, theThe Quantum 350 Wireless didn’t prove uncomfortable and will thus be able to accompany the players without any problem. We still feel JBL’s lack of experience in this sector with some design approximations, but the whole remains globally convincing.

A real software solution

Despite JBL’s youth in the gaming headset market, the brand has done things the right way by offering a real software solution to accompany its products. So just install the JBL QuantumEngine driver to customize the options of the Quantum 350 Wireless headphones.

The interface has a completely assumed retrofuturistic look and highlights a 10 band equalizer associated with different presets dedicated to different uses (music, FPS, movies, etc.). Virtual 7.1 spatialization is also customizable, as is the microphone and his return.

The delay before the headphones go to sleep can also be changed and the software displays the remaining battery level. All the previously mentioned settings can also be saved in profiles. However, it is not possible to associate them with our games and applications.

We salute here the service of JBL which offers a very complete software for his helmet Quantum 350 Wireless and which will allow you to personalize it very simply while benefiting from numerous settings.

A flawless connection

JBL uses a very classic 2.4 GHz connection here, similar to what is found with most manufacturers. During our few days of testing, this connection has proven to be perfectly reliable and no cuts came to spoil our gaming sessions. It is also possible to move several meters away from the receiver without losing the connection.

On the autonomy side, the brand announces up to 22 hours away from the charger. This value is just right compared to the best models on the market, but in practice it is possible to use the headset for several days before having to recharge it. Charging itself will take approximately 2 hours to reach 100% if the battery is completely empty.

Note also that thanks to its dongle USB, the Quantum 350 Wireless is also compatible with PlayStation 4 and PS5 and Nintendo Switch.

Headphones that love bass

JBL has little more to prove when it comes to audio. The Quantum 350 Wireless headphones are no exception and offer a very qualitative sound performance. Unsurprisingly, the sound signature of the headphones particularly highlights the low frequencies, but does so in such a way that they remain well defined and do not eat away at the rest of the spectrum.

Sounding very fair overall, the JBL Quantum 350 Wireless shows perfectly comfortable listening to music with a well-defined and warm sound. These good qualities logically allow it to be perfectly suited for video game use where the beautiful emphasis on low frequencies will make you feel the explosions very frankly in your favorite FPS. It’s even sometimes too much on certain types of sounds, but it will be possible to correct this using the equalizer.

Stakes, we also appreciate the good stereophony and the sound stage wide enough to enjoy excellent immersion. The helmet also offers a overall convincing virtual 7.1 spatialization in terms of immersion, but which always tends to distort the sounds too much. Finally, the passive sound insulation is also very correct.

On the side of the removable microphone, we find here something very classic which will be more than enough to chat with our playmates. As always, you will find below a sound extract recorded with the microphone of the JBL Quantum 350 Wireless.
